It’s the day of Mairi’s wedding and despite the best-laid plans, things do not run smoothly. Mairi has to round up the pigs in her wedding dress after they run loose around the yard, and ends up getting a lift on the back of Lafferty's bike after Chic's car breaks down. However a special guest makes Mairi’s day. With Sally’s prompting, Sheila makes the connection between Niall and Sneddon. Meanwhile, Mr Spinetti is back and has big plans that could change Glendarroch forever.
